CHAPTER 13. SERVO CHECK MODE
A built-in servo key unit provides the cost-effective and convenient diagnostic functions without
optional loader. When the servo amplifier is in servo-off, It is possible to enter the servo check mode
by the servo key unit. Editing sequence is as follows.
13-1. SELECTION OF SERVO CHECK MODE
13-2. DETAILED DESCRIPTION OF SERVO CHECK ITEMS
The check mode is composed of 15 items (C-00 ~ C-14). It performs the various kinds of check
function such as H/W check, in/out check and parameter initialization.
Operation
Push the MODE key to change from "status display"
to mode selection level.
1. The pre-saved mode is displayed at LED.
Each modes are scrolled sequentially by
UP/DOWN key.
2. Select the "CHEC" mode and push the SET key.
3. Push the SET key. "C-00" is displayed.
4. Each check mode no. is scrolled sequentially by
the UP/DOWN key (C-00~14).
Stop at the check mode no. to be checked.
5. Push the SET key.
It displays the contents of selected check mode.
You can do a check function.
6. Push the MODE key and return to the level 4

Description
00 C-00
* SINE-WAVE CHECK
Check the sine-wave for motor control.
It displays the value which varies from -1024 to +1024 (4 times/revolution).
Usage : used to check the servo amplifier at factory setting.
01 C-01
* SPEED FEEDBACK CHECK
Check the speed feedback and encoder A/B phase for motor control.
The dot means the reverse(CCW) rotation.
If the dot is not displayed, it means the forward(CW) rotation.
Usage : used to check the encoder A/B phase wiring mistake.
02 C-02
* ENCODER UVW SIGNAL CHECK
Check the encoder U/V/W phase for motor control.
When the servo motor shaft is rotated slowly toward clock-wise direction by hand,
U/V/W phase signal is displayed sequentially as follows
100 --> 101 --> 001 --> 011 --> 010 --> 110 --> 100 --> repeat
Usage : used to check the encoder U/V/W phase wiring mistake.
03 C-03
* ANALOG INPUT CHECK
Check the analog input port. The dot means the negative voltage.
Usage : used to check the analog command input.
